Kansas City Chiefs RB De'Anthony Thomas (hamstring) is expected to make his regular season debut in Week 5 against the San Francisco 49ers after missing the first four games due to a hamstring injury. Special teams coach Dave Toub is reasonably confident Thomas will perform well in a punt-return role. "We got him back there enough where he had to make some catches, he made some people miss, he got hit one time and spun out and got a touchdown," Toub said. "He's got a little bit on tape, so people know about him."
